I have connected a device using Modbus RTU over TCP. Occasionally there are timeout errors which Ignition is picking up and showing in the tags.,I have bound a control to.  
Let’s say I have an ON/ OFF tag bound to a checkbox. **When an error occurs, the checkbox will toggle by itself. ie, checking and unchecking by itself.**  
How can I avoid this?
